TL;DR: A decision support system for the selection of a diagnostic or therapeutic test or intervention, referred to as studies, is supported by identifying a relative number of cases in which significant results were obtained in studies having the same indications as mentioned in this paper.
Abstract: A decision support system for the selection of a diagnostic or therapeutic test or intervention, herein called studies, is supported by identifying a relative number of cases in which significant results were obtained in studies having the same indications. In particular, an ordering physician requests a study for a patient and specifies indications for the study, such as symptoms and a potential diagnosis. The number of studies performed, including those on other patients, for which results were significant for the same indications out of the total number of studies performed for the same indications is provided as feedback to the ordering physician. This feedback relates actual patient results to the appropriateness of the study. A decision support system in a health care information management system receives, from an ordering physician, an order for a study to be performed on a specified patient and indications for the study. The received indications for the selected study are used to access a database of result codes for previous studies having the same indications, including studies performed on other patients. A result of the comparison of the selected study and specified indications to the result codes database is then sent to the ordering physician. Decision support may be enhanced by using data extracted from existing scientific literature. In one embodiment, the decision support system is part of a health care management system that supports structured order entry for use by the ordering physician and a structured data entry module for entering result codes into the database.
TL;DR: Patients prefer receiving both normal and abnormal examination results from the physicians who ordered the examination rather than the radiologist, and they prefer to receive very detailed examination results rather than a brief summary in lay terms.
Abstract: OBJECTIVE. It has been suggested that radiology reporting practices would be improved if radiologists were to discuss the results of an examination directly with the patient. The attitudes and preferences of patients with regard to direct communication with the radiologist are not well-defined. The purpose of this study was to survey patients about their preferred method of receiving radiologic results. MATERIALS AND METHODS. An anonymous survey was distributed to adult patients undergoing contrast-enhanced CT or MRI over a 2-week period in June 2013. RESULTS. The response rate was 58.4% (642 responses). For normal examination results, the preferred mode of communication was a telephone call from the ordering physician (34.1%); only 12% of respondents opted for a telephone call from the radiologist, and 2.6% chose a face-to-face meeting with the radiologist. For abnormal test results, the preferred mode of communication was also a telephone call from the ordering physician (49.8%); 14.4% of respondents se...
TL;DR: The use of urine toxicology screens (UTSs) may be useful in the diagnosis or monitoring of patients with established or suspected substance abuse, such as those with cancer as mentioned in this paper.
TL;DR: It is suggested that prospective audits of blood component orders can help reduce inappropriate transfusions and can be a valuable educational tool for the ordering physicians as well as for residents in training.
TL;DR: Urine-DOA testing led to a justified change in management in 0/133 instances (95% confidence interval 0%-2.3%), calling into question the need for this test in the ED setting.
Abstract: BACKGROUND: Drug abuse is a frequent factor in emergency department (ED) visits. Although commonly performed, qualitative testing of urine for drugs of abuse (u-DOA) is inherently limited in its ability to establish the identity, timing or dose of substances used. Previous studies have demonstrated these limitations, but their designs cannot be used to determine whether the results of u-DOA tests affect physicians' patient care decisions. Our objective was to determine the impact of u-DOA testing on the care of patients who present to the ED. METHODS: All adults 18 years of age or older who had u-DOA testing in 2 urban teaching EDs were eligible. Victims of vehicular trauma or sexual assault were excluded. Just prior to communicating the results of u-DOA testing for a patient, an investigator interviewed the ordering physician or consultant physician about the patient care plans for that patient. Test results were then revealed, and the questions immediately repeated. This design isolated the impact of knowledge of u-DOA test results on physicians' patient care decisions. Any intended changes in patient care plans reported by the interviewed physician were compared to a priori criteria for substantive change and then subsequently reviewed by an independent expert to determine whether that change was justified. RESULTS: Of the 110 u-DOA test results studied and the resultant 133 opportunities to influence physician management plans, there were 4 reported changes in management. One management change was judged to be substantive, but none of the 4 reported changes were considered by the independent expert reviewer to be justified. Urine-DOA testing thus led to a justified change in management in 0/133 instances (95% confidence interval 0%-2.3%). CONCLUSIONS: Urine-DOA is rarely helpful in guiding patient care decisions in the ED. The results of this study call into question the need for this test in the ED setting. Language: en
